MILTON PERLMAN gm vm ATTORNEYS United States Patent 3,265,082 VALVE ANDDIVERTER CONSTRUCTIGN Milton Perlman, Detroit, Mich, assignor to NileCorporation, Royal Oak, Mich. Filed Apr. 24, 1964, Ser. No. 362,380 2Claims. (Ci. 137119) This application, a continuation in part of myprior United States patent application, Serial No. 312,424 of September30, 1963, relates to valves or faucets for use in outletting through asingle spout, with a diverter construction incorporated therein fordiversion to a secondary or spray line through a diverter tube in thespout.

It is an object of the present invention to provide a simplified valveand diverter construction characterized by the location of the diverterin the spout mouth of the valve and the incorporation of the divertertube in the spout of the valve, such tube leading, through the valve, toa secondary line.

Such novel form of diverter construction enables selective flow throughthe mouth of the spout or through the secondary water line, such as aspray tube, as desired.

For an understanding of the valve and diverter construction hereof,reference should be had to the appended drawings which show a preferredembodiment.

In these drawings:

FIG. 1 is an elevation view of the valve showing the spout and thesecondary water line in place.

FIG. 2 is a view in vertical cross-section of the assembled valve withthe secondary water line shown diagrammatically and with a portion onlyof a spout and diverter tube being shown.

FIG. 3 is a large scale sectional view of the spout mouth and diverterconstruction therein located.

FIG. 4 is a section view on line 4-4 of FIG. 3.

FIG. 5 is an exploded view of parts at the spout mouth.

FIG. 6 is a fragmentary sectional view of a sealing element.

The primary valve The valve hereof, hereafter referred to as the primaryvalve, as shown best in FIG. 2, comprise (FIG. 6) a cylindrical shell orcollar or sealing element 10 surrounding a cylindrical valve body orcore 12. Vertical inlet bores not here shown (FIG. 1), adapted to beconnected at their lower ends to hot and cold water inlet lines 18 and20, open into the dome shaped rounded convex upper end or valve seat 22of the body 12 and provide inlet ports. These are not herein showninasmuch as the inlet parts form no part of the present invention and inaddition are more specifically and in full detail shown in the aforesaidapplication.

A third vertical bore 23, for outletting, also opens to seat 22 of thebody and at its lower end opens to a transverse horizontal passage orbore 24 herein referred to as a first water outlet passage, arranged toopen laterally.

Against seat 22 of body 12 is a concave primary valve member 25 which isseated to be shifted or rotated for control purposes. From its upperconvex surface, upwardly extends a central stem 26 providing a handgrip.

Valve member 25 has inlet openings not herein shown and an outletopening 27. The location of the openings in valve member 25 determinesrelative communication among the inlet passages and the outlet passage24.

The foregoing parts generally are like those described in the aforesaidapplication.

Diverter At this point We now describe certain of the new parts of thevalve disclosed herein for the first time and which Patented August 9,1966 enable diversion of water flow as desired and as will hereafter bedescribed.

It has previously been stated that primary valve body 12 has a firstwater outlet passage 24 opening laterally to the outside of the valvebody 12.

In addition, there is a second water outlet passage 70 opening laterallyto the outside of the valve body 12. In other words, there are twolater-ally opening water outlet passages 24 and 70 with the firstpassage 24 being above the second passage 70.

The valve body has not only the first vertical waterv outlet passage 23which opens at its lower end to the lateral passage 24, but also has asecond vertical water outlet passage 71 which opens at its upper end tothe second lateral passage 70.

Between collar 10 and valve body 12 are two separate annular reliefpassages 72 and 73, one above the other, and each communicatingseparately with a lateral passage as shown. Thus, a path is providedcomprising parts 23, 24 and 72; and a second path is provided comprisingparts 73, 70 and 71.

Collar 10, previously referred to as a cylindrical shell, surrounds andseals both passages 72 and 73.

Carried by and sealed to said collar is a spout 76 which has one endfixed to the collar 10, with such end encompassing both annular passages72 and 73.

Within spout 76 as shown best for the time being in FIG. 2 is a divertertube 77, which opens to and seals the lower passage 73 and thuscommunicates with passages and 71.

In addition to the foregoing parts and adapted to be provided for usewith the valve herein shown there is a secondary water line 79 connectedto the second water outlet passsage 70 by means of vertical passage 71.Such water line is generally provided for a spray tube or spray head 80(FIG. 1) located at the end of line 79.

Incorporated within line 79 is a spray or secondary valve 82 which isnormally closed and spring loaded but which may be opened manuallywhenever desired as for example when it is desired to spray throughspray head 80.

In valves of this sort, particularly for kitchen sink use but for otheruses as well, it is desired to incorporate a diverter which operates insuch a way that normally Water flows out of the mouth 83 (FIGS. 1, 3, 5)of spout 76 and does not flow out of spray head 80 of secondary line 79,but with the parts arranged in such a way that when secondary valve 82,which is normally closed, is manually pressed open, the flow of water isdiverted to the secondary water line 79 and spray head 80, with waterflow from spout mouth 83 being inhibited.

At this point therefore, there is described a diverter construction.Novel hereto is the fact that the diverter is located within thegenerally vertically extending and downwardly opening spout mouth 83.Normally, with valve =82 closed, water iiows out of spout mouth 83 andthere is no flow out of spray head 80. The diverter in the spout mouthoperates automatically, when valve 82 is opened, to shut off flow fromspout mouth 83 and to direct all flow through spray head 80. Suchdiverter construction will now be described with particular ref erenceto FIGS. 3-4 which show such diverter construction in enlarged scaleview and in detail.

FIG. 3 shows the spout 76 disposed generally horizontally and formedwith a generally vertical downwardly opening mouth 83.

FIG. 3 also shows diverter tube 77 having a closed end 78 disposedwithin the spout 76 and having an orifice S4 in the lower surface ofsuch closed end, with orifice 84 opening downwardly and located withinthe spout mouth 83.

A unitary diverter element 89 has a housing 90 also within the spoutmouth. Such housing has a nipple 91 in orifice 84 of diverter tube 77,and has its lower end seated in an adapter 92 fixed in spout mouth 83,with the lower edge of the housing 90 being adjustably clamped in placeagainst a flange 92a of a nipple portion 93 of adapter 92 .by a threadedaerator ring 94, there being a resilient washer 95 between such ring 94and the adapter nipple 93. The upper portion of the diverter housing 90seats firmly against a resilient washer 96 and thus against the lowersurface of the diverter tube 77, flattened for this purpose.

In housing 90 is located a diaphragm 101 whose outer edge is clamped inplace in the housing 90 by a fixed spacer 103 and a fixed support 105,so that the outer edge of diaphragm 101 is not movable.

The inner edge of such diaphragm 101 loosely engages a piston 106 towhose upper end is integrally secured the inner edge of an annularpiston plate 107 whereby the upper end of the piston 106 is 'veryconsiderably enlarged, considerably more than the enlarged lower end 108of the piston 106. Thus the piston 106 with its somewhat enlarged lowerend 108 and its greatly enlarged upper end 107 is a differential areapiston, whose operation will later be described.

Mounted in housing 90 is a piston seat 110 in the form of a conical ringwhose inner annular edge defines a discharge opening 111 adapted to beclosed by the lower enlarged end 108 of piston 106 when the latter islifted to the dotted line position shown from the full line positionshown.

In order to back up the diverter tube 77 against the thrust imparted toit by the threading up of the aerator ring 94 onto the adapter plate 92of the spout mouth 83 and thus upwardly thrusting the diverter housing90 against the lower surface of the diverter tube v77, the latter is soformed that its end 78 backs up against the upper surface of the spoutmouth 83 so as to be backed up by it.

Slots 112 in the housing wall 90 between spacer 103 and piston seat 110communicate the interior of the housing 90 with the spout mouth topermit water flow from the spout into the interior of the housing 90through slots 112 and thus selectively down through the opening 11]. inpiston seat 110 and out through the aerator ring 94 for conventionalflow, or alternatively up through housing nipple 91 and into divertertube 77 for diverted flow to the secondary line 79 when secondary valve82 is opened.

The diverter operation is as follows:

With secondary valve 82 closed as is normal, piston 106 is in its fullline lowermost position due to the effect of gravity and there is noforce to counteract this efiect. Accordingly discharge opening 111 inpiston seat 110 is open and water flows through spout mouth 83, throughslots 112 of diverter housing 90, and out through the opening 111 inpiston seat 110 and out downwardly through aerator ring 94. No waterflows up through the housing 90, nipple 91 and into diverter tube 77,and thus no Water flows in the secondary line 71.

When valve 82 however is opened, secondary line 79 and diverter tube 77are opened, and piston 106 is lifted to close the opening 111 in pistonseat 110 by the differential area effect, responsive to the fact thatthe upper end 107 of the piston 106 is greater in area than the lowerend 108. With the piston so lifted to close the opening 111 in pistonseat 110, the flow of water entering the housing 90 through slots 112 isupward in housing 90, between the inner edge of diaphragm 101 and piston106, exiting through nipple 91 and into diverter tube 77 and out throughsecondary line 79 to spray head and at the same time is diverted so asno longer to flow down and out of the spout mouth through aerator shell94.

Now having described the valve with diverter construction hereindisclosed, reference should be had to the claims which follow.

I claim:

1. In spout and diverter construction;

a discharge or outlet spout extending generally horizontally and havinga generally vertical spout mouth with a downwardly directed dischargeopening;

a secondary valve normally blocking said diverter tube and openable asdesired to permit flow in said tube;

a diverter in said spout mouth below said orifice;

said diverter being a unitary diverter element comprising a housinghaving a bottom valve opening and containing a vertically movabledifferential area piston valve which moves up to seal the valve openingfrom below and down to expose said valve opening;

said piston, when down, as is normal, permitting full flow through saidvalve opening and discharge opening and no flow into the diverter tubeorifice and adapted to be moved upwardly automatically on the opening ofsaid valve by water pressure to close said valve opening and saiddischarge opening to inhibit flow through said discharge opening and topermit full flow into the diverter tube orifice;

said diverter, including its housing and valve as a unitary diverterelement, being insertable as a unit into the spout mouth upwardlythrough its discharge openand a ring threaded onto said spout mouth atthe discharge opening to retain said unitary diverter ele ment in saiddischarge opening.

2. In a construction according to claim 1;
